CORD BUSH

PROBLEM TO BE SOLVED: To provide a cord bush having high sealability and easy to be attached.SOLUTION: A cord bush 1 has a flange part 12 having a cylindrical insertion part 11 which is inserted to a cord port 101 formed with a cylindrical shape; a cylindrical first projection 31 which is formed on one edge of the insertion part 11 and contacts with an edge face of the cord port 101; a cylindrical second projection 32 which is formed on an outer peripheral edge of the edge face of the first projection 31, facing the cord port 101; and a third projection 33 which extends toward the insertion part 11 from the edge face of the second projection 32, has inner diameter which is larger diameter than outer diameter of the insertion part 11 and is formed with smaller diameter than the outer diameter of the cord port 101, and an annular lip 13 which has an opening 13a having the inner diameter formed with a smaller than the outer diameter of the cord 110 inserted into the cord port 101 and is arranged on an inner peripheral surface of the insertion part 11.SELECTED DRAWING: Figure 1 【課題】高いシール性を有するとともに、容易に取り付け可能なコードブッシュを提供すること。【解決手段】コードブッシュ１は、円筒状に形成されたコード口１０１に挿入される円筒状の挿入部１１と、挿入部１１の一方の端部に形成され、コード口１０１の端面に当接する円筒状の第１突出部３１、第１突出部３１のコード口１０１と対向する端面の外周縁に形成された円筒状の第２突出部３２、及び、第２突出部３２の端部から挿入部１１に向かって延出するとともに、その内径が挿入部１１の外径よりも大径であって、且つ、コード口１０１の外径よりも小径に形成された第３突出部３３を有するにフランジ部１２と、コード口１０１に挿入されるコード１１０の外径よりも内径が小径に形成された開口１３ａを有し、挿入部１１の内周面に設けられた円環状のリップ１３と、を備える。【選択図】 図１
